Abstract
Alcoholic agent is excessively harmful for humans. Considering the level of harmfulness, an efficient and flexible alcohol detection method is very essential. In this context, a hollow core photonic crystal fiber (HC-PCF) based optical sensor is designed for detecting alcohol in beverages as well as in any liquid samples, which is constructed with slotted air holes in the cladding section and a square hollow core. The presented PCF structure yields an extremely high sensitivity of 89.85% with ultra-low confinement loss of 10−14 cm−1 in THz frequency range of 0.4 to 1.2. To design and investigate the sensing properties of PCF based sensor COMSOL multiphysics software v.5.3a is used with a finite element method as a solver. Design methodology of presented PCF geometry and fabrication feasibility are also addressed.
